Application November 8, 1951, Serial No. 255,420

Claims. (Cl. 30195) This invention relates generally to hair cuttingdevices and more particularly to a combined comb and thinning cutter fortrimming hair.

In cutting hair, the first step is the back combing of the hair and thesecond step is to remove the bulk of the hair with a conventionalclipper. The final and most important step is the thinning of the hairand the trimming thereof. It is necessary that the barber hold the combin his left hand and a thinning shears in the other and then operateboth of them in perfect harmony. This operation requires a very skilledman to perform a decent job. It is now a practical impossibility for theordinary person to perform the thinning and trimming operation withoutleaving steps in the hair. The thinning shears is used with the comb totaper a strand of hair. The operation of a comb in one hand and athinning shears in the other at an elevated position is very tirin Itis, accordingly, an object of my invention to provide a combined comband thinning cutter which is simple in construction, economical in cost,economical in manufacture, and easy to operate.

Another object of my invention is to provide a combined comb andthinning cutter which works in perfect unison and which may be operatedby one hand.

Another object of my invention is to provide a combined comb andthinning cutter which may be operated by a relatively inexperiencedperson to trim a person's hair.

Other objects of my invention will become evident from the followingdetailed description, taken in conjunction with the accompanyingdrawings, in which Fig. l is a plan view of my novel combined comb andthinning cutter;

Fig. 2 is a side elevational view of my novel combined comb and thinningcutter;

Fig. 3 is an enlarged plan view of the head of the cutter shown in Fig.l

Fig. 4 is a transverse sectional view of the head of the cutter shown inFig. 3; and

Fig. 5 is a plan view of a modified form of head for my novel cutter.

Referring now to the drawings, I show in Figs. 1 to 4 inclusive a baseplate 1 having curved comb teeth 2. An intermediate cutting and bearingplate 3 is juxtaposed on the base plate 1. The intermediate plate 3 haslaterally spaced cutting bars 5 above and in parallel relationship withthe comb teeth 2 of the base plate 1. The cutting bars 5 are engaged bytransversely extending, spaced, parallel teeth 6 having V-slots 6a cutin the outer ends thereof mounted on support bars 7 which extendparallel to the comb teeth 2 and the cutter bars 5. The support bars 7are attached to a transversely movable plate 8 slidable on the top ofthe intermediate plate 3. The support bars 7 are attached to the movableplate 8 by fastening members 10. The movable plate 8 has a recessedportion 9 on the back side thereof for receiving the end 11 of a cammember 12 disposed on the end of a handle 13. The movable plate 8 hastransversely aligned, rectangular shaped slots 25 for receiving guidingpins 14 attached to the intermediate plate 3 by screw members 15.

The base portion 16 of a stationary handle 17 is attached to theintermediate plate 3 by screw members 18. The base portion 16 of thestationary handle 17 has a transversely extending, bored, cylindricalportion 19 internally threaded on one end 21 thereof for nestingPatented Nov. 9, 1954 2 a coil spring (not shown) which is engaged by anextending portion 261 of the cam member 12 to urge the mov able handle'13 away from the stationary handle 17. A screw 26 is threadably engagedwith the threaded end 21 of the member 19 to adjust the tension of thespring therein.

The base portion 16 of the handle 17 has an upwardly extending threadedshaft 22 for receiving an apertured cover 23 which is secured by a wingnut 24 in threadable engagement with the threaded shaft 22.

Any conventional form of mechanism may be used for moving the movableplate 8 with the cutter teeth 6 thereon to and fro in translation. Thegist of my invention lies in the combination of the curved comb teethwith the particular arrangement of the cutter bars and transverselyaligned cutter teeth.

My invention is particularly utilized after the bulk of the hair hasbeen removed by a conventional clippers. Strands of hair are thenselected and the comb teeth 2 are run through the strands while themovable handle 13 is operated, thereby moving the transverse plate 8 toand fro to move the ends 6a of the thinning teeth 6 over the edges ofthe cutter bars 5 on the intermediate plate 3 to thin out and taper thehair. A comparatively inexperienced operator can perform a very goodtrimming job with my novel cutting and trimming device. By spacing thecutting teeth a predetermined distance apart, only a predeterminedamount of hair in a given strand is cut, thereby providing a thinningaction. The V-shaped slots 6a in the ends of the cutting teeth 6 areprovided in order that hair may be bunched and a better cutting actionresults.

In Fig. 5, I show a modified form of my novel combined comb and thinningcutter wherein the cutter bars 5 in Fig. l on the intermediate plate 3are replaced by spaced, stationary, thinning cutters 30 transverselyaligned with spaced thinning cutters 31 attached to a movable plate 32which is moved to and fro in the same manner as the plate 8 in Fig. 1.The only change in the modified form of my invention is a newintermediate plate 33 with transversely extending, spaced cutter bars 30at right angles to the comb teeth 34 instead of the cutter bars 5parallel with the comb teeth 2 as shown in Fig. 1. Both the cutter bars30 and the thinning cutters 31 have the distal ends 35 and 36 thereofslotted in V-shape in order to bunch the hair therebetween to provide abetter cutting action.

It will be evident from the foregoing description that I have provided anovel combined comb and thinning cutter for trimming hair which has abase with curved comb teeth to eliminate steps in the hair, spacedthinning cutters disposed transversely to the comb teeth, and a novelarrangement of parts for trimming and thinning out the hair and taperingthe sides thereof for use by an inexperienced person.

Various changes may be made in the specific embodiment of my inventionwithout departing from the spirit thereof or from the scope of theappended claims.

What I claim is:

l. A hair cutting and trimming device comprising a fixed frame, a fixedplate-like member supported on said frame, said plate-like member havingcutting bars extending from one edge thereof, a movable member supportedon said plate-like member, said movable memmember having a plurality ofher having a plurality of support bars attached to one edge andextending outward therefrom in substantially parallel relation to saidcutting bars, spaced cutting teeth attached to the sides of saidsupports, cutting edges on the distal end of said teeth, and means toslidably oscillate said movable member on said fixed plate intranslation whereby said cutting edges slide over said cutting bars tocut hairs engaged by said cutting edges, thereby thinning the hair.

2. A hair cutting and trimming device comprising a plate-like basemember having comb teeth extending from one edge thereof, anintermediate plate-like member supported on said base member, saidintermediate member having cutting bars extending from one edge thereofin parallel relation to said comb teeth, a movable member supported onsaid intermediate member, said movable support bars attached to one edgeand extending outwardly therefrom in parallel relation to said combteeth, spaced cutting teeth attached to said support bars, said cuttingteeth having cutting edges, and means to oscillate the movable member onthe intermediate plate in translation whereby said cutting edges engagesaid cutting bars and whereby when a strand of hair is disposed betweensaid bars, the hairs engaged by the edges of said teeth are cut and thehairs disposed between said teeth remain intact.

3. The hair cutting device recited in claim 2 wherein cutting teeth areattached to the cutting bars, said teeth on said cutting bars havingcutting edges on the distal end cooperating with the cutting edges onsaid movable member teeth.

4. The hair cutting device recited in claim 1 wherein said cutting edgesare V-shaped.

5. The hair cutting device recited in claim 2 wherein said cutting edgesof said teeth are V-shaped.
